INA Roller Bearing Shaft Location Washer 73 mm OD 45 mm ID WS81209

The INA WS81209 Roller Bearing Shaft Location Washer is an essential bearing component designed for use in axial cylindrical roller bearing assemblies. This washer provides a reliable shaft positioning solution by delivering high axial rigidity and ensuring the precise location of the shaft within bearing arrangements subjected to high axial and shock loads.

With an outer diameter of 73 mm and an inner diameter of 45 mm, this washer fits accurately onto mating components, creating a secure interface and optimizing the load distribution. Its dimensional attributes make it suitable for direct integration into compact mechanisms where axial space is limited, supporting applications that require both compactness and robust performance.

The washer's configuration allows it to be mounted separately from the bearing, providing flexibility during installation and facilitating maintenance processes. This characteristic is especially valuable in industrial assemblies where timely servicing and part replacement may be demanded to minimize machinery downtime.

INA WS81209 is engineered for use in one-direction axial loading scenarios where radial loads are not present, such as in heavy-duty mechanical, fluid power, and tooling systems. It is optimal when standard axial deep groove ball bearings no longer meet the load carrying requirements, ensuring both operational reliability and assembly rigidity. The washer is made to meet industry expectations for quality and durability, supporting robust industrial environments including manufacturing, construction machinery, and power transmission setups.

Its advanced design enables use as part of a direct bearing arrangement or as a supporting element in cost-effective standardized assemblies. The sure fit and ease of separation of components make it equally well-suited for new machine builds and ongoing maintenance projects.

This washer is well aligned for typical industrial, manufacturing, and mechanical workshop use, where load certainty and shaft positioning precision are critical parameters.
